There are several UX issues with the actual editor menu system (and in particular the contextual menu)
a. The way the shortcuts are represented (they should be aligned to the right of the item) is no standardized (and they should be adapted to the user operating system: for instance Ctrl key does not exist on a Mac and the equivalent on Mac is the Command key)
b. The contextual menu is not aware of the pop-up position. They should open to the left or right of the mouse cursor based on the space available on the right of the window.
1. Follow the best practices on UX to design contextual menus
2. Make the contextual menus adaptable to the pop-up position.
